ClawScan runs +command-backed scanners in Docker by default. `PATH` lets it locate Docker; +`DOCKER_HOST` is only needed when the local Docker setup uses it. + +## Understand the sandbox boundary + +There are two separate execution boundaries: + +1. OpenClaw runs `security.installPolicy.exec` as a trusted local child of the + Gateway/install process. The normal OpenClaw agent tool sandbox does not run + or isolate this command. +2. ClawScan runs command-backed scanners such as SkillSpector in its own Docker + sandbox. The built-in `clawscan-static` scanner runs inside the trusted + ClawScan policy process. + +OpenClaw downloads, clones, uploads, or extracts a candidate into a temporary +staging location before install commit. It sends the absolute staged +`sourcePath`, its `file` or `directory` kind, and the host-declared `skill` or +`plugin` target type to ClawScan over stdin. ClawScan uses that target type +directly instead of trying to rediscover it from a manifest. + +For a command-backed scanner, ClawScan automatically bind-mounts every existing +absolute path passed to the scanner. The staged target is mounted read-only at +the same absolute path inside the container; the scanner's temporary result +directory is mounted writable. An invocation is conceptually equivalent to: + +```sh +docker run --rm \ + --mount type=bind,source=/tmp/openclaw-install/package,target=/tmp/openclaw-install/package,readonly \ + --mount type=bind,source=/tmp/clawscan-results,target=/tmp/clawscan-results \ + ghcr.io/openclaw/clawscan-runtime:latest \ + skillspector scan /tmp/openclaw-install/package \ + --format json \ + --output /tmp/clawscan-results/report.json +``` + +Operators do not need to add a `--sandbox-mount` for `sourcePath`. That option +is only for extra operator-owned paths required by a custom scanner or judge. + +### Containerized OpenClaw Gateway + +When the OpenClaw Gateway itself runs in a container, the policy executable +must exist inside that container at the configured absolute `command` path. +The default nested scanner sandbox additionally requires the Docker CLI and +access to a Docker daemon. + +If the Gateway container uses the host Docker socket, a staged path that exists +only in the Gateway container cannot be bind-mounted into the scanner +container. Docker resolves bind-mount sources in the daemon host's filesystem, +not the calling container's filesystem. The same rule applies to ClawScan's +writable temporary result directories. + +Use one temporary root that is bind-mounted from the Docker host into the +Gateway at the same absolute path, set the Gateway's `TMPDIR` to that root, and +include `TMPDIR` in the policy command's `passEnv`. OpenClaw staging paths and +ClawScan result paths will then both be visible to the host Docker daemon: + +```json5 +passEnv: ["PATH", "DOCKER_HOST", "TMPDIR"] +``` + +For example, mount `/var/lib/openclaw-install-tmp` into the Gateway at +`/var/lib/openclaw-install-tmp` and start the Gateway with +`TMPDIR=/var/lib/openclaw-install-tmp`. Do not use a container-only `/tmp` for +either staging or ClawScan results in this nested-Docker topology. + +Alternatively, treat the outer Gateway container as the isolation boundary, +install every selected command-backed scanner inside it, and explicitly disable +ClawScan's nested Docker sandbox: + +```json5 +args: ["openclaw-install-policy", "--sandbox", "off"] +``` + +This alternative runs scanner commands directly inside the Gateway container. +Use it only when that outer environment is intentionally isolated and +disposable. Do not disable the sandbox merely to work around a missing Docker +daemon or mismatched staging paths. + +For npm plugin installs, OpenClaw calls the policy before mutation with an +`npm-package-metadata.json` file, then calls it again for the resolved package +and installed dependency tree. ClawScan identifies the metadata stage from its +plugin/npm file-stage shape, then validates the complete host tuple before +allowing the lightweight path: npm origin, immutable network npm source, +package content role, matching package names, and the exact metadata filename. +A malformed metadata-stage tuple fails closed instead of falling through to an +ordinary file scan. Valid metadata uses the built-in static scanner without +Docker and is not presented as a scan of plugin code. The later package and +dependency-tree calls keep the full profile. Dependency packages are exposed +in a dedicated scan view so normal `node_modules` exclusions cannot hide their +code. Local `plugin-file` requests never match the metadata shortcut. A +dependency-tree phase with no installed runtime dependencies returns an +explicit allow/info response because the package itself was already scanned in +the package phase. +For managed npm roots, the dependency view omits only OpenClaw's exact +host-validated `node_modules/openclaw` peer symlink; other links escaping the +staged root fail closed. Safe links within the staged root are dereferenced +into stable copies so scanners inspect the code the installed package will use. + +On native Windows, the default profile visibly degrades to +`clawscan-static` with the sandbox disabled because the Linux Docker runtime +cannot consume native Windows staging paths. The response is `warn`, requiring +OpenClaw to obtain explicit confirmation, and includes a finding for this +reduced coverage. Explicit `--scanner` or +`--sandbox` arguments remain operator-owned and disable this automatic fallback. + +To use an operator-owned profile, add explicit arguments: + +```json5 +args: [ + "openclaw-install-policy", + "--config", + "/absolute/path/to/.clawscan.yml", + "--profile", + "install-policy", +] +``` + +The configured command is the composition point for multiple checks. ClawScan +does not claim an active-scanner singleton and does not replace other policy +engines. Operators can select several scanner adapters in one profile or wrap +several policy checks behind their configured executable and combine their +responses deterministically. Install-policy profiles must express decisions +through scanner gate rules; judge-backed profiles fail closed because ClawScan +does not define a canonical judge-verdict-to-policy mapping. + +## Request and response contract + +The command accepts OpenClaw's complete policy payload, including: + +- `targetType`: `skill` or `plugin` +- staged `sourcePath` and `sourcePathKind` +- `source` and `origin` metadata +- request kind, install/update mode, and requested specifier +- target-specific skill or plugin metadata + +ClawScan uses the host-declared target type, so staged plugin files and +dependency trees are scanned as plugins even when they do not contain a +top-level plugin manifest. + +Successful scans return: + +```json +{"protocolVersion":1,"decision":"allow"} +``` + +Warning gate rules return `decision: "warn"` with a required reason and +optional bounded findings. OpenClaw owns the confirmation prompt and resumes +the install only after explicit user confirmation. Blocking gate rules return +`decision: "block"` with a required reason and optional critical findings; +blocks are not overridable. Invalid requests, scanner errors, skipped required +scanners, empty results, and unknown gate verdicts return a valid block response +with a fail-closed reason. OpenClaw also fails closed if the executable cannot +start, times out, exits nonzero, emits malformed output, or does not support a +returned protocol decision. + +The policy process never prompts. It does not issue approval tokens, negotiate +capabilities, or maintain install phase IDs. Its only approval signal is the +top-level protocol-v1 decision; OpenClaw owns all acknowledgement state and UI. + +## Scope + +OpenClaw routes supported third-party skill install/update paths and supported +plugin install/update sources through `security.installPolicy`.
